ABRAHAM H. PHILLIPPI, OF READING, PENNSYLVANIA.

GAS-REGULATOR FOR RAILROAD-CARS.

Specification of Letters Patent No. 29,401, dated July 31, 1860.

To all whom it may concern:

Be it known that I, A. H. PHILLIPPI, of Reading in the county of Berksand the State of Pennsylvania, have invented an improved gas-regulatorto be applied to the gas-cylinders used on passenger-cars or to anyother reservoir wherein gas is confined under a high pressure; and I dohereby declare that the following is a full,'clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, forming part of this specification.

Figure 1 represents a side elevation. 2 represents a plan. transversesection.

My invention consists in having two plain steel or metallic disks orplates a a, riveted together with a metallic ring 5, between them.

0 is a brass nipple secured to the plates or disk (4, and having athread on the outside for the purpose of attaching the pipe leading fromthe cylinder to the regulator.

(Z is a nipple attached to the disk a containing a wrench for adjustingthe valve 6, which may also be used to shut off all communicationbetween the cylinders and the burners. This valve is conical and has aleather washer f on its face to prevent the face and seat of the valvefrom being injured by any gritty substance that may happen to be carriedalong with the gas as it passes through the regulator.

9 represents a fiat place on the valve stem as shown on section and planfor the purpose of admitting the gas into the space between the disks aa.

it represents a hole drilled to the center of the stem of the valve, tomeet another hole 2' which admits the gas into chamber 7', from whenceit passes through the hole is, into the pipe Z, to the burners.

m is a wrench for adjusting the valve to supply the required number ofburners.

n is a small gland for the purpose of pack- Fig. Fig. 3 represents a ingthe stem of the wrench m, to prevent the gas from leaking through. Thegland n is screwed down by means of the nut O as in any ordinarystuifing boX.

The operation of this regulator is simple the pipe conveying the gas toit is attached to a socket or nipple 0, and the pipe conveying the gasfrom the regulator to the burners is attached to'th'e nipple (Z. WVhenthe gas is turned on it passes through the fiat opening G into the spacebetween the disks a a, the pressure causing them to expand or divergeand thus close the valve 6, which is adjusted by means of a thread onthe stem by the wrench m so that it will just allow A..- the properquantlty of gas to pass through the opening G to supply the burners. Asthe pressure in the cylinder decreases by the gas being burned out thevalve 6 gradually opens allowing the gas a free passage through theopening G thus giving burners a regular supply so they will not blow butburn with the same intensity whether there is five hundred lbs. pressureper square inch in the cylinder or only twenty-five lbs. per squareinch.

The object of this regulator is more es pecially for railroad cars, orelsewhere where the gas is forced into the receiver under a pressure ofseveral hundred pounds or so that a small receiver will contain a verylarge quantity of gas.

What I claim as my invention is In combination with the plane-diskspringplates at a, and their inclosed space, the valve 6, with itswasher f, flat space 9, and openings h, i, for the purpose of regulatingthe flow of gas from the receiver, to the burners, whatever may be thepressure upon the gas, substantially as herein described andrepresented.
